Feature Request: Add a receipt to Expense

[XxXxfredxXxX]

Current State

Currently, I can just add a Note to each Expense. To Identify Later what I was buying.

Proposal

It would be nice to add a receipt to an Expense. In this way I would know what I bought in a Category without the need to write down what I bought. It could just be a Picture of the receipt or some fancy OCR to just save the Item Names.

This would help me (and I hope some others too) to find out what expensive things I bought at the grocery Store like two weaks ago.

English is not my native Language so if something is written a little weird, please feel free to reach out to me, so I can rephrase my request.
